Hair pin winding
WebSep 5, 2024 · The hair-pin winding has become prominent in drive-train motors for electric and hybrid vehicles, with many creative examples in manufacturing. Although ‘push-through’ hair-pin coils have long been used in other industries, especially in heavy machines, it is probably fair to say that relatively few changes took place before the more recent impact … WebModeling of Hairpin Winding in Ansys Motor-CAD This paper demonstrates the bespoke modeling capabilities in Motor-CAD for the analysis and design of hairpin windings. The modeling method of the hairpin winding using Motor-CAD is shown, as well as design rules and checks in the software.

The wire needs to be shaped into a hairpin before it can be automatically inserted into the stator core slot, and the end needs to be twisted and welded.
WebFeb 23, 2024 · A hairpin motor is an electric motor whose stator winding is done with hairpins instead of round wires. Hairpins are rectangular and large compared to wires. … WebThe difference between hairpin motor and round wire motor is that the wire used in the stator winding of the motor is different. Traditional motors use round wires, while hairpin motors use flat rectangular wires. Drive systems with large volume, heavyweight, and weak power are unpopular in the new energy vehicle market.
